Identity Management in Information Systems
Tran, Thanh Quang ; Bartík, Vladimír (referee) ; Burget, Radek (advisor)
This thesis deals with the issue of identity management on the web and the implementation of an information system that solves this issue. The proposed information system utilizes Keycloak for identity management and delegating the authentication process centrally to a third party. Thanks to Keycloak, external identity sources can be integrated using widely used protocols such as SAML 2.0 and OpenID Connect. The information system itself is built on a microservices architecture, where individual microservices are implemented in the Python programming language. The web client of the information system is implemented in the Vue.js web framework with the Vuetify extension, which is used for easy creation of the web user interface.

A software tool for checking the secure settings of the parameters of the selected database
Hlavica, Adam ; Štůsek, Martin (referee) ; Šeda, Pavel (advisor)
This thesis deals with the design and implementation of a software tool for best practice database configuration checking. The theoretical part describes database technologies, their applications and existing solutions in the field of automated database configuration checking. Furthermore, possible configurations of the PostgreSQL database system are presented with a focus on security. The practical part shows the design of a program with the necessary requirements and its implementation in Python. The final chapter focuses on a practical demonstration of the program deployment.

Web Application for Editing and Biometric Signing of Documents
Denk, Aram ; Burget, Radek (referee) ; Bartík, Vladimír (advisor)
The bachelor thesis deals with the design and development of a web application for editing and biometric signing of PDF documents using a signature tablet. The thesis focuses on the study of the principles of web application development which includes a comparison of JavaScript frameworks, it also studies manipulation with PDF documents and the issues surrounding biometric signatures. Existing solutions for biometric signing of documents are analyzed. Based on this analysis, the requirements for a new web application are determined and its design is carried out. This is followed by a description of the actual implementation, which is mainly done in JavaScript using the framework React. After implementation, the application is tested and the results are evaluated.

Design of the e-Voting system and its Legal Specifics
Váňa, Vojtěch ; Harašta, Jakub (referee) ; Loutocký, Pavel (advisor)
The thesis focuses on the design of the electronic voting system and its legal specifics. The work focused on the legal aspects of electronic voting, such as voter authentication, data security and guarantee of anonymity of votes. In the theoretical part of the thesis, a survey of the historical development of e-voting and an analysis of the experience of countries that have already implemented this system was conducted. Furthermore, the thesis shows the current situation in the Czech Republic with electronic voting and analyses the relevant legislation related to this issue. The practical part of the thesis contains a concrete proposal for an electronic voting system that combines technological innovations with legal requirements.

Classroom student identification using passwordless authentication
Kamenská, Veronika ; Kurečka, Radomír (referee) ; Travěnec, Jiří (advisor)
This thesis deals with the passwordless authentication of a Masaryk University student within the Simulation Centre of the Faculty of Medicine. In the introduction the concepts of authentication, passwordless authentication, multifactor authentication are explained. Subsequently, these methods are compared with respect to security and the most optimal method suitable for implementation in teaching is selected. A mobile application was created in Flutter environment which will be used by the students for authentication. At the same time, an algorithm was designed to test the application in practice. A pilot testing was carried out focused on the real deployment of the application in the teaching of the Masaryk University Simulation Centre. The results of this testing were then statistically evaluated.

Decentralized Autentication System Based on Blockchain
Mračna, Štefan ; Malinka, Kamil (referee) ; Januš, Filip (advisor)
This work studies the effects of the integration of blockchain technologies into authentication systems, specifically biometric authentication systems for unlocking doors. The work analyzes different blockchain and authentication technologies and determines which of these technologies are appropriate for this purpose. The work also compares centralized and decentralized authentication systems. A decentralized authentication system which includes blockchain technologies is then proposed and a simplified version of the system (where individual devices in the system are represented by processes) is implemented. Testing of effectiveness, security, reliability and memory usage is then conducted under different conditions.

Person Identification
Svědiroh, Stanislav ; Honec, Peter (referee) ; Richter, Miloslav (advisor)
This thesis focuses on the person identification based on faces. The aim is to create a working solution of person identification for the authentication purposes utilizing the Microsoft Kinect v2 sensor. It contains a summary of the most used algorithms for facial data description and their comparison. Thesis also proposes a PC program that controls the sensor and collects the facial data, saves them, manages keypoint detection and their comparison.

Current security trends in mobile networks
Jirkovská, Šárka ; Sobotka, Jiří (referee) ; Doležel, Radek (advisor)
This master's thesis deals with the issue of the security of GSM and UMTS mobile communication systems. In the thesis the principles of the authentication and encryption of both the mobile systems are described. Further, the constituent algorithms used for identity verification, key generation and encryption are mentioned. The commonly used algorithms are described along with their weaknesses. In the following part of this thesis, well-known attacks on GSM system are mentioned. In the part where UMTS system is dealt with one can find the algorithms used in this system to increase the security of transmitted data and authentication in comparison with GSM system. Therefore the whole process of authentication and encryption is described separately. In the last part the creation of programming models of authentication and encryption in GSM and encryption in UMTS is described. These models are created in the environment of Matlab version 2009b.

Attribute based authentication
Chwastková, Šárka ; Hajný, Jan (referee) ; Dzurenda, Petr (advisor)
This thesis deals with attribute based credentials. It describes attribute systems, their entities and properties generally. The work concentrates specifically on the attribute system Identity Mixer. The process of communication of the attribute system Identity Mixer is implemented in the language of JavaScript. Application is the web visualization, which describes protocols, entities and generally computes protocols of Identity Mixer with inputs of small numbers or predefined large numbers.
